Dell pc pointer jumps while and after typing


Make sure your fingers/palms aren't grazing the touchpad as you're typing. What's probably happening is your hands are too close to the touchpad, making the computer think you're using the mouse, and thus jumping the cursor around.

The cursor jumps around on my ASUS K501J notebook.


Step 1


1. Open Mouse by clicking the Start button, clicking Control Panel, clicking Hardware, and then clicking Mouse.
2. Click the Pointer Options tab, and then do any of the following:

To change the speed at which the mouse pointer moves, move the Select a pointer speed slider towards Slow or Fast.
• To make the pointer work more accurately when you're moving the mouse slowly, select the Enhance pointer precision check box.
To speed the process of selecting a choice when a dialog box appears, select the automatically move pointer to the default button in a dialog box check box.
To make the pointer easier to find when you move it, select the Display pointer trails check box, and then move the slider towards Short or Long to decrease or increase the length of the pointer trail.
To ensure that the pointer doesn't block your view of the text you're typing, select the Hide pointer while typing check box.
To find a misplaced pointer by pressing the CTRL key, select the Show location of pointer when I press the CTRL key check box.

Step 2


If you are using touchpad, try reducing the Touchpad sensitivity and check

1. Click on the "Start" icon in the lower left corner of the screen. Select "Control Panel." Next select "Mouse" under "Hardware and Sound." You can also left-click the touchpad while the cursor is anywhere on the desktop. From that screen, choose "Mouse Pointers."
2. Select the "
Buttons" tab at the top of the dialog box that opens. This shows the type of touchpad device installed on your laptop.
3. Set the touchpad for right or left-handed use from this dialog box. You can adjust the double click speed of your computer as well. When you finish making any changes, click "
Apply."
4. Pick the "
Device Settings" tab from the dialog box now. You can see the touchpad for your Vista machine highlighted on this screen. Select "Settings."
5. Read the information provided in the next dialog box. It gives you options for tapping your
touchpad, using the buttons, scrolling, pointer motion and sensitivity.
6. Make any changes you want from the various topics. When you make a change, click "
Apply." Click "OK" when you finish making all your changes.
7. Do some work on your computer for a while, If the touchpad is still too sensitive, return to the "Mouse" menu and continue to adjust the settings until you get them just the way you want them.


Step 3

If the issue persists try to perform a clean boot and check whether the issue is still persists.

Follow the steps mentioned in the article given below.

Runaway touchpad on HP laptop.


I have the same problem. An external mouse does not behave erratically. If the touchpad is wearing out, will a replacement touchpad solve the problem, or does the circuit board need replacing?

Try going into control panel & find the mouse section. See if you can adjust the sensitivty down. You may have a program built in from acer to adjust this too. I reccomend turning off the tap feature on the mouse pad. When they get old they get real touchy. If turning the sensitivity down doesn't work, you can try & see if there's an updated driver or re-install the old one. If all else fails,it's time to head to ebay to find the touch pad.

Cursor on my keypad jumps around


If your cursor moves erratically on the screen (for example, if it jumps around the screen, moves at varying speeds, or selects items on its own), perform the following steps:

1. Clean the surface of the touchpad with a dry, soft cloth to remove grease, sweat, moisture, or other liquids.

2. Adjust the sensitivity of the touch pad:.

a. Click the Start button and click Control Panel.

b. Click Printers and Other Hardware.

c. Click Mouse.

d. When the Mouse Properties window appears, click the Pointer Options tab.

e. Under Select a pointer speed:, click to move the slider bar closer to Slow.

f. Click OK.

g. Check to see if the touch pad still behaves erratically.

3. If the touchpad still caused the cursor to behave erratically, attach an external mouse to your computer and restart your computer. Use the external mouse to see if your cursor still moves erratically.

4. After connecting an external mouse, uninstall the touchpad driver from the Device manager listed under the "mice and other pointing devices" category and restart the Computer.

5. Download the Touchpad driver compatible to the Operating System installed on the Computer from the manufacturer's site and install it after restarting the Computer.


Good luck!!!!!!!!!!
